Letλ> 0 andbe the Bessel operator on R+:= (0,∞). We first introduce and obtain an equivalent characterization of CMO(R+,x2λdx). By this equivalent characterization and by establishing a new version of the Fréchet-Kolmogorov theorem in the Bessel setting, we further prove that a functionb∈ BMO(R+,x2λdx) is in CMO(R+,x2λdx) if and only if the Riesz transform commutator xxxx is compact onLp(R+,x2λdx) for allp∈ (1,∞).
